IMPROVEMENT IN CAR-AXLE LUBRICATORS.

Specication forming part of Letters Patent No. 151,641, dated June 2, 1874 application tiled Y May 23, 1874.

u CASE B.

To all-whom it mag/concern:

Be it known that I, J osEPH WHITAKER, of Woonsocket, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in (lar-Axle Lubricators; and I do hereby declare the following to be a full and exact description of the same, reference being had to the accompanying drawings forming part of this speciication, in which- Figure l is a longitudinal section of a carboX provided with my invention. Fig. 2 is an end elevation of the journal, and Fig. 3 a perspective view of the lubricating device detached.

Similar letters of reference in the accompanying drawings denote the same parts.

My invention has for its object to provide a cheap, simple, and elicient device for lubricating the journals of car-axles. To this end it consists of a horizontal arm connected to the outer end of the axle or journal by a suitable pitman, and guided by a horizontal pin entering a vertical slot in the end of the carboX, the arm receiving a vertically-reciprocating motion when the axle revolves, and being always held in a horizontal position, the reciprocatiou alternately plunging the arm into the contents of the reservoir, and elevating it to the lower side ofthe journal, thereby lubricating the latter. The arm is provided with suitable porous or fibrous material for absorbing and elevating the oil, all of which I .will now proceed to describe.

In the drawing, A represents the axle-box, having the ordinary reservoir B. O is the journal, having a pitman, D, pivoted eccentrically to its outer end, and extending downward, asv shown. E represents a horizontal arm rigidly attached to the lower end of thepitman D, and projecting inward under the journal, parallel with the latter, as shown in Fig. l. F is a horizontal pin projecting outward from the pitman D into a vertical slot in the outer end of the box, said slot being formed, in the present instance, in a plate, H, attached to the box, as shown in Fig. 1. Ihe arm E is provided with suitable absorbing maA terial I, which may consist of a strip of fibrous material, or a brush, attached in any desired manner. When the axle revolves the arm E receives a vertically-reciprocating motion, and is alternately elevated and depressed, its absorbing material coming in contact with the lower side of the bearing, and being plunged into the oil in the reservoir, the journal being thus thoroughly lubricated. The arm E is guided in a vertical line by the pin F and its slot 5 hence said arm reciprocates vertically, and is always held in position parallel with the journal.

The device, being attached and guided only at theouter end of the axle and boX,is adapted to be applied readily, and constitutes a cheap and efficient lubricator.

I am aware that Letters Patent have been granted to Michael Egan, dated November 6, 1855, for a lubricator somewhat similar to mine, and I therefore disclaim said invention.

I claim as my invention- The pitlnan D, having the horizontal arm E and pin F rigidly attached thereto, and supported at the outer end of the axle, in combination with the guide H, substantially as described.

JOSEPH WHITAKER.
